The most important feature in your hot tub is the water. If it’s not crystal clear and ready to use, nothing else matters. That’s why clean, healthy water is the foundation for all of Dimension One’s advanced hydrotherapy designs. Enjoy the cleanest water in the industry that is also the easiest to maintain.
The Vision Cartridge offers D1® spa users a natural and effective way to reduce the use of chemically-based water sanitation systems. Used in combination with D1® ozone systems, the Vision Cartridge uses silver catalyst technology that kills 99.96% of impurities on contact. One Vision Cartridge lasts up to 6 months and can reduce the need for extra chemicals by 60% for cleaner, healthier and softer water.
Available as an optional addition to the spa filter on any Dimension One Spa.
The hot tub ozone system is one of the most important advances in the portable spa industry. All three D1® systems have ozone generators, often called “ozonators” for short. They’re called that because they produce ozone gas; ozone is a form of oxygen. Though ozone is a form of oxygen, it kills germs and purifies your portable spa’s water. Chlorine does the same thing, of course. However, using ozone to sanitize your water means you can reduce the amount of chlorine you use. Too much chlorine isn’t good for your hair, skin or the environment.
UltraPURE® is the best water management system available in a swim spa today. UltraPURE® is more than just an ozone generator; it’s a fully engineered, patented water management system similar to the systems used throughout European municipal waste facilities. It has a dedicated filtration and water management system, processing about 10,000 gallons per day. After filtering the water, this system vigorously mixes ozone and water three times to ensure ozone comes in contact with every drop of water – ozone doesn’t just kill bacteria, it burns it up! That means the water in your spa is not just clean, it’s crystal clear.
Improving upon the industry standard, D1® offers the patented UltraPure® water management system. UltraPure® is more than just an ozone generator; it’s a fully engineered water management system similar to the systems used throughout European municipal waste facilities. This hot tub filtration system mixes ozone and water three times to ensure ozone comes in contact with every drop of water to provide the purest water possible, 24 hours a day. That means the water is not just clean, it’s crystal clear. The best part is, UltraPure® silently purifies while you’re in the tub for an exceptionally quiet experience. US Patent: 5,665,228
As the pioneers of the use of ozone in hot tub water care, we know that not all ozone systems are created equal. Through the use of this natural, oxygen-based system, ClearZone® PRO significantly reduces the need for chemicals by fighting and oxidizing impurities 47% more efficiently than standard ozone systems.
